Frequently asked questions
Below are the questions that come up most often about how the tools work, what happens to your text, and how far to trust a score. If yours is not here, the contact page has an address that reaches a person.
Is AI Detector free to use?
Yes. Every tool on ZeroGPT is free, with no account, no trial period and no credit card. There is nothing to unlock.
Is my text or file uploaded anywhere?
No. AI Detector runs entirely in your browser using JavaScript. Your content is read from the page, processed on your device, and discarded when you close the tab.
How accurate is it?
It is a strong signal, not a verdict. AI Detector measures statistical patterns, and patterns can be wrong in both directions. Use the result as one input into your own judgement, especially when the stakes are high.
Does it work on my phone?
Yes. The layout adapts to small screens and the tools are built to work with touch. Very large files may be slower on an older phone.
Which languages are supported?
ZeroGPT is available in English, French, German, Spanish, Italian and Portuguese. The text tools work best on English but handle other Latin-script languages reasonably well.
